Analisis Perhitungan Quantity Take-Off Menggunakan Building Information Modeling (BIM) Pada Proyek Jalan Tol Indralaya – Prabumulih

Penerapan BIM pada proyek Pembangunan Jalan Tol merupakan upaya Kementrian PUPR dalam peningkatan daya produktifitas dan daya guna perencanaan dan pembangunan proyek konstruksi jalan bebas hambatan melalui implementasi Information and Comunication Technology (ICT). Melalui Badan Pengatur Jalan Tol (BPJT) memberikan tugas kepada Badan Usaha Jalan Tol (BUJT) untuk menerapkan BIM pada Pembangunan Jalan Tol Indralaya – Prabumulih. Dengan BIM diharapkan akan meminimalisir kesalah dalam perhitungan QTO yang mengakibatkan kesalahan dalam penentuan biaya proyek. Metode BIM dilakukan dengan menggunakan software pendukung yaitu Autodesk Revit untuk melakukan pemodelan 3D dan 5D (QTO) yang nantinya hasil perhitungan volume metode BIM akan di bandingkan dengan perhitungan volume metode konvensional. Studi kasus dilakukan pada Box Culvert STA. 0+126 pada Pembangunan Jalan Tol Indralaya – Prabumulih. Berdasarkan hasil penelitian didapatkan perbedaan volume secara keseluruhan sebesar 0,03% dimana perhitungan dengan Autodesk Revit lebih besar dibandingkan perhitungan konvensional. Persentase perbedaan pada pasangan batu kosong (Blinding Stone) sebesar 0,01%, beton struktur kelas E sebesar 0,01%, batang baja tulangan BJTD-40 sebesar 0,02%, struktur beton kelas C-2 dan urugan material berbutir (granular backfill) sebesar 0%. BIM dengan Autodesk Revit dapat melakukan perhitungan QTO secara otomatis yang sudah terintegrasi dengan desain 3Dnya, sehingga meningkatkan ketelitian dalam penentuan Rencana Anggaran Biaya (RAB)

Research Agenda for Studying Open Source II: View Through the Lens of Referent Discipline Theories

In a companion paper [Niederman et al., 2006] we presented a multi-level research agenda for studying information systems using open source software. This paper examines open source in terms of MIS and referent discipline theories that are the base needed for rigorous study of the research agenda

An overview of Mirjam and WeaveC

In this chapter, we elaborate on the design of an industrial-strength aspectoriented programming language and weaver for large-scale software development. First, we present an analysis on the requirements of a general purpose aspect-oriented language that can handle crosscutting concerns in ASML software. We also outline a strategy on working with aspects in large-scale software development processes. In our design, we both re-use existing aspect-oriented language abstractions and propose new ones to address the issues that we identified in our analysis. The quality of the code ensured by the realized language and weaver has a positive impact both on maintenance effort and lead-time in the first line software development process. As evidence, we present a short evaluation of the language and weaver as applied today in the software development process of ASML

Investigating e-business practices in tourism :a comparative analysis of three countries

This study examined the behaviour of tourist companies in relation to the adoption of e-business technologies and applications. The study aimed to identify groups of companies with homogenous behaviour among three European countries (Greece, Portugal and Norway). Based on data from a European survey, the study employed two-step cluster analysis which revealed 14 clusters of common behaviour (five clusters in Greece, five in Portugal and four in Norway). These clusters were named as: Leaders’ ‘Technology Experts’, ‘Fast Adopters’ ‘Beginners’, ‘Late Adopters’. In Norway, the group ‘Late Adopters’ also included companies characterised as ‘Beginners’ in the other two countries. We suggest further investigation among European countries in order to reveal more groups of similar behaviour toward e-business adoption

Unleashing the Effectiveness of Process-oriented Information Systems: Problem Analysis, Critical Success Factors, Implications

Process-oriented information systems (IS) aim at the computerized support of business processes. So far, contemporary IS have often fail to meet this goal. To better understand this drawback, to systematically identify its rationales, and to derive critical success factors for business process support, we conducted three empirical studies: an exploratory case study in the automotive domain, an online survey among 79 IT professionals, and another online survey among 70 business process management (BPM) experts. This paper summarizes the findings of these studies, puts them in relation with each other, and uses them to show that "process-orientation" is scarce and "process-awareness" is needed in IS engineering
